解決：

查看Python路徑相關環境變量的意義。

• PYTHONHOME ：指定 Python 的標准庫。
• PYTHONPATH ：用於擴充 Python 查找模塊文件的路徑。

這里是導入 site 模塊時出錯，所以應該在 PYTHONPATH 上增加 site 模塊的路徑。

查找site相關文件的路徑：

[root@tZ etc]# find / -name site.py*
/usr/lib64/python2.7/site.pyc
/usr/lib64/python2.7/site.py
/usr/lib64/python2.7/site.pyo

增加路徑到環境變量：

[root@host-10-10-18-131 Python-2.7.5]# export PYTHONPATH=$PYTHONPATH:/usr/local/python2.7.5
[root@host-10-10-18-131 Python-2.7.5]# make -j 4
./python -E -S -m sysconfig --generate-posix-vars
